With.
The braking principle of rear axle is as follows, when the oil pressure for controlling the first oil pressure chamber 23 by hydraulic regulating valve is reduced, the second oil
When the oil pressure of chamber 23 being pressed to increase, left direction is mobile together for left and right piston 17,18, and clutch steel disc 27 divides with clutch friction plate 28
From to cut off power；At the same time, left and right piston 17,18 pushes brake plunger 22 to be moved to the left simultaneously urges brake steel disc
35, braking steel disc 35 compresses brake strip 36 and mutually generates very big frictional force, and brake strip 36 is forced to tend to be static
It is motionless；Due to brake strip 36 and the normal spline engagement of long interior outer gear ring 21, long interior outer gear ring 21 is also stopped with brake strip 36
It is firmly motionless, to play good braking effect, complete machine is made quickly to stop.
When needing maintenance and maintenance replacement, upper cover 5 is opened, locking steel wire 9, half-axile sleeve 6 is taken out, makes left clutch
4 reserve mobile space；Then the left clutch 4 of side direction movement to the right, then takes out the left and right limiting card in long in outer gear ring 21
Spring 13, then make the side direction movement to the left of outer gear ring 21 a distance in long；Then bolt 38 is removed, makes brake casing 33 with after
Axle housing 2 separates, that is, can be taken off left brake 3；Left clutch 4 is finally moved to the left, makes the clutch active on left clutch 4
Hub 31 is separated with rear axle beam 7, that is, can be taken off left clutch 4.After taking out left brake 3 and left clutch 4, it can to left braking
Device 3 and left clutch 4 carry out maintenance and maintenance replacement.The operation principle and process on right side is identical as left side.Complete maintenance
It after maintenance, gradually installs by reverse procedure, no longer repeats herein, the maintenance dimension of fragile part inside entire rear axle can be completed
Repair work.
The above, only specific embodiment of the utility model, not makes in any form the utility model
Limitation, on the basis of not departing from the technical solution of the utility model, made simple modification, equivalent variations or modification are fallen
Enter the protection scope of the utility model.
